Clutch-controlling lever T is mounted pivotally, upon fixed Stand .7n l5 E?. .is l'lcretofore, it is provided rb-it a cam to 3o-act with the tail ot clutchM f that as the .tiiangc-slnzft con;- j-nei'cs a i v cion and the said *ail nukes contact with the tace of said cam the latter snail at; te tra the clntchficver upon its pivots imi, so as to Withdraw the chufh .h trom engagen'ient with the vra-rm.; i and permit the changvshaft to stand ai fest., with the clut-shdcvcr held in its rriraf'nsl position 'by the controlling atci c is mounted npon the pivot c' l o' aff shown bestI lotion to arm 43 of the tripping i controllin lever is provided. When such shoulder 1s thus engaged the latch holds clutch-controlliiig lever 257 in itsrvvorking position shown 1n Fig. 2, to unclutch the Worm-gear 7 5 from the change-shaft so that the latter shall stand at rest. A contracting spiral spring tends to draw the latch forward and to eep it engaged With the 'said arm, as in Figs. 1, 2 and 3.

The connection between the latch and the weft-detector devices c0mpr1scs, in this 1nstance, a connector which is connected at its upper end to tlie arm 43 iXed on the trippin rockshaft 411. The connection is establis ed by means of a collar g on the upper portion of the connector g, the collar and connector being securely fixed together by means of a clamping-screw g12 and the collar being pivotally engaged with the said arm 43. The connector g is in thc form of a. rod or wire having its lower end-portion formed into a loop g, Figs. 3 and 4, receiving a pin /i projecting from an arm i in connection with the latch c. W hen arm 41 is swung forward by thc action of the weft detector devices., 'thereby rocking tripping roclshatt 411 so a s to s wing arm 43 upward, the upward movement of connector g causes the latch c (if unlocked) to be swung out of engagement with arm e, thereby releasing the clutch-controlling lever so that the latter yields to permit clutchdcvcr 252 to bc actuated by its spring 256 so as to clutch the constautlv-running worin-gear 75 to the change-shalt. Connect-1.1 fl may be adjusted up or down relative to collar g to regulate the action of the sario and of latch 0.

is soon as the tail of the clutch-lever passes an uy from the cani-tace of the clutchcoatrolling lever '257, the weight of arm c of the latter causes said lever 257 to swing into its working position again, and latch c is caused by spring f to snap into engagement with arm e, thus locking'fho lever in readiness to act upon the tail of clutchlevcr Q52 as it comes around al the close of a rotation of the change-shaft.

A feature of the, invention is a provision for yielding to prevent the parts from l'cing strained or broken in case the arin 4l :lawul bc swung forward at a time when thc lalci. c is locked against movement. in this instance the arin i is made capable of yielding. lt shown as mounted pivotally rat, /c upon an arm m forming a rigid part of latch c, and as boing held normally in contact with a tixed stop n upon arm m by means of a coutracting spiral spring o, one end of which is connected to a projecting part of arm i and the other to a projecting part of the carrying-arm m. Should the connector g] be moved upvvard at a time when the latch c is locked and incapable of moving, the spring i will yield to permit arm i to turn .lpon pivot .1c connecting it with the arm m.

Referring now to the safety-lock devices in which t e invention mainly resides,--As here embodied, a lock for the latch c is shown at p, Figs. 1, 8 and 4. It consists of an arm which is pivoted at p npo'n a rearward extension of stand al, with capacity tor vertical swinging movement, the limits of which are fixed bv stops p2, p2, upon stand d. The forward en. of said arm is constructed for engagement with a portion ot' latch c. When the latch is forward in engagement with arm c of the clutch-eontrollingl lever 257, as in Figs. l and 3, and the lock itself is in its lowest. position in engagement` with the latch, as in said figures the lock prevents the latch from disengaging from arm e. Consequently the clutch-controlling lever 257 is held locked in its working position and the cl1a11ge-shaft remains at rest. When the lock is raised out of its working position, the lat/ch is thereby unlocked so that it is rendered capable of being disengaged from arm e of the clutch-controlling lever to allow the clutch-devices to clutch the change-shaft to the constantly revolving worm-gear 75.

The actionof the lock is controlled by a lock-controller g, which in this instance is constituted by a rocking-cam pivoted at q, upon stand d, and engaging by its cam-face with the underside of a pin 713`carried by lock p. The gravity of the lock, aided by the tension of a spring if deemed advisable, keeps the pin p in contact with the said cam-face, se that .the shape ot the latter determines the position of the. lock. The ramfaee has a prominence which is located intermediate two depressions. Then either depression is presented to the-pin p3 the lock is free to assume or retain its working position occupied in Fig 8. As the controller is rocked from one extreme position to the other, the projection in passing the pin p3 raises the lock, thereby disengaging it from the latch. As the projection passes out of engagement with pin p3 the lock is allowed to drop back toward its working position.

The lock-controller q is connected with the shipper-handle 2O by means of a connector if, the upper end of which is connected to the link 19. The connection ot' connector if with link 1i) by means of a collar ff on the connector, securedl adjustably thereon by means of a clamp Ascrew j and having the lower end of link 19 pivotaly engaged therewith. linen the shipper-handle is moved into its on position occupied by it in Fig. l. the movement of link 19 upward not only moves the shipper-lever 129. and bra ire-lever 'lol to start ille weaving instrumentalities, ont serves' through connector 72 to rock the lockcontroller f] into the position occupied by it in Fig. fi in sncii sition of the lockcontrollcr the fion? dein' fave iA fented to the tim lia i the latch cannot be jarred, by the action of the loom-mechanism in weaving, or knocked, or brushed out of engagement with arm e. Consequently release of the clutch-controlling lever 257 by accident or mischance, and resulting clutching of the change-shaft to the cpnstantly rotating worm-gear 75, cannot occur. When the shipper-handle is thrown ofi', the movement of pivot 192 lowers link 19 and connector q2, and, in addition to permitting the shipper-lever and brakelever to act to arrest the Weaving instrumentalities, rocks the lock-controller q from its position in Fig. 3 to that occupied by it in Fig. 4. As the lock-controller is thus rocked, its prominence raises the lock momentarily, the lock being left free to drop again by the depression which is then resented to pin p. During the momentary e evation of the lock the latch is unlocked, and at this time it is capable of being disengaged from the clutchcontrolling lever by the action of the weftdetector devices. If it is not disengaged While the lock is elevated, it is locked again by the immediately following descent of the lock, and it continues locked during the stoppage ot' the ionic until the weaver restarts the latter by throwing on the shipper-handle. Consequently he may work around the loom, and operate thesame by hand, without danger of accidentally starting-up the changeshaft. In brief, therefore, the lock holds the latch locked while the loom-shipper is on and also while it is offf that is to say at all times except during an intermedi-atc portion of the movement ot' the loom-shipper.

The loop or slot g in the lower end of the connector g is vertically elongated so that it permits lost-motion between the said connector and pin h. Consequently, when the tripping rock-shaft is rocked the toe 4G thereof acts to throw oil" the shipper-handle before the lower end-wall of said loop or slot engages with the said pin L. This gives a sui"- ficient lead to the lock-controller q to enable its prominence to litt the lock in time to permit Withdrawal of the latch by movement transmitted through connector f7.

The latch resets itself automatically as soon as controlling lever 257 resume. iis working position, and the lock resets itself automatically as soon as the latch has reset itself. v

I do not claim broadly herein devices for tripping the loom-shipper and also tripping the change-shaft drive into action to operatc the, change-shaft, and a lock operatively controlled by said loom-sliipper preventing establishment of such relations atan improper time; or a change-shaft drive fncluding a clutch and clutch-controlling means, loom-shipper, and devices by which the loom-shipper is tripped, and by which also said clutch is tripped to establish drivt i ing relations between said drive and the change-shaft, having combined therewith e lock for said clutch-controlling means, itsel operatively controlled by said loom-shipper, preventing establishment of such relations at an improper time, inasmuch as I have made broad claim thereto in my ifo-pending application for patent for improvements in looms filed Aug. 28, 1912, crinl No. 717,444.
